hmm
some good info in here.
Im heading on a 400K round trip tomorrow. Now im going to check the pressures before i go, just in case.
most of my driving so far has been on hwy usually an hour and a half to two hours round trip. about 60-65MPH no funny front end feeling yet.

edit:I think im at about 1400KM.. on it... thats about 800-900 miles.
